Your home is a place you want to keep secure, but getting all the high-end security gadgets and services available to help you do that is a pricey endeavor. This weekend, roll your own DIY security system. It's more fun and it'll save you some money.

There are many ways to secure your own on the cheap, from alarms to surveillance to clever tricks. A combination of all three should do the trick, so let's take a look at your options.

Make Your Own Alarm System

There is no shortage of DIY alarms, so you really just have to decide how and why you want to be alerted. This aduino-based alarm is motion-based an will send you a text message if it detects an intruder. If you've got a Mac, you can use a clever app called SecureHome that detects noise levels and sounds an alarm if they reach a specified level. If you're worried about specific items getting stolen and want to alarm them individually, you can't go wrong with this $2 motion-detecting alarm. It requires some very minor soldering and a tilt switch, but it's easy enough for just about anyone to create can hide just about anywhere. You can also use the source devices (impact alarms) with no modifications at all to secure your windows.
